I Specmcation of Letters Patent.

Application filed January 81, 1911. Serial No. 805,839.

' Patented Aug. 27,1912.

invented a new and useful Improvement in Shredders for Paraflin-Wax and the Like, of which the following is a specification.

This invention relates to a device for.

shaving or granulating solid material, such asparafiin, soap, chocolate and other substance.

The purpose of the invention is to provide a device whereby wax or other similar substance can be readily shaved or commmuted I to rotate the same.

intoum'form shavings or pieces and which device 15 so s1mple and cheap 0% production.

that it can be supplied, with each cylindrical cake of wax or similar substance and may be discarded when that cake is used up, thusobviating the necessity of an expensive and complicated device which must becleaned, and sharpened, or if not cleaned becomes unsightly and unsanitary.

The invention comprises a device having the structural features hereinafter described and claimed.

In the accompanying drawin Figure 1 is a side view partly in section, 0 the simplest form of my device showing the same applied to a cylinder of para 11 or the like; Fig. 2 is a plan view of the same; Fig. 3 .is a section on the line 33, Fig. 2; and Fig. 4 is a side view, partly in section, of a modification,

In the drawings 1 indicates the cake of paraflin, soap or other substance to be reduced to' shavings, and which for the purpose of my invention is cylindrical. The shaver comprises a cylindrical cup 2 of such diameter as to fit loosely over the cake 1 and having an annular flange of such length as to have a substantial bgaring on the cake and be guided thereby. The periphery of the cup is roughened, such as by fluting or corrugating the same, as shown at 3, in order that it may be firmly grasped The end or head 4 of the cup is provided with one or more cutters, preferably arranged radially as shown in Fig. 2, and adapted when the cupis rotated on the cake to shave thin slices or shavings therefrom. These cutters can be most easily and cheaply formed by making the cup of thin sheet metal and slitting the head radially and bending one edge inwardly as\ shown at 5, and the other slightly outwardly, as at 6, Fig. 3, to form thecutter and leave a slit 7 through which the shaving passes.

The entire cup can be struck up from thin sheet metal by a simple die operation,

and at a total cost of a few cents. Hence it can be su plied without extra cost with each cake 0 parafiin, sea is used by merely placing it over the end of the cake and rotating the same on the cake, or rotating the cake 1n the cup, while pressing the same endwise together, thereby cutting the substance off the end of the cake in thin shavings.

Fig. 4 shows the addition of means for automatically pressing the cup and cake together endwise. It comprises a threaded rod 8 secured centrally to the cup 2 and enaging a threaded hole in a piston or 01- ower 9 arranged to bear against the end of the cake 1, and provided with means, such as radial ribs or flanges 10, to prevent relative rotation of the follower and the cake. Obviously when the cup 2 is rotated the follower 9 is caused to travel toward the cup ilf the manner of a nut, and presses the cake against the cup.' The pitch of the thread on the rod 8 determines the thickness of the shavings cut from the cake.

The device described is intended principally for shaving paraffin or like wax for laundry, floorand other purposes. Such waxes are now generally put up in thin rectangular. or like cakes and are shaved by hand with an ordinary knife. Not only is. this slow and tedious, but the shavings are very non-uniform in thickness, and when in haste are likely to be entirely too thick for the intended purpose. With my device the shavings can be cut as thin as desired, depending on the width of the slit 7, and can easil be as thin as tissue paper,-or mere fla es. Thus the wax much more efiectively serves its purpose, Whether for laundry purposes or for waxing floors. The only change necessary is that the wax be molded in cylindrical instead of thin cakes of rectangular form, which will not add to its cost. The shaving device can be so cheaply reduced that it can be furnished with eacli cake of wax without extra cost, thereby acting as an incentive to more ex or the like. It

tensive use of the wax. Although made of very cheap material the device is nevertheless suficiently durable to shave the entire cake with which it is supplied. The cake need be wrapped for-sale in no s ecial manner, and when being shaved can e exposed, on the end only, keeping the wax clean and free from dust.

The cup can be used either side up, on account of having the edges of the slits 7 bent in opposite directions. This enables it to be used'upside down for shaving various substances, by either rotating or reciprocating it on a cake or body of the substance to be shaved. In this case the shavings accumulate in the cup and can be discharged when the cup is fu 1, thereby measuring the shaved substance.

What I claim is:

1. A device for shaving or shredding wax and other substances, comprising a cylindrical cup of sheet metal arranged to fit loosely over a cylindrical cake and having a flange of such length as to have a substantial support thereon, and provided ou its head with openings having one edge bent inwardly to form cutters, a threaded rod secured to said cup, and a follower enrod and arranged to bear against the op osite end of the cake.

2. A device or shaving or shredding wax or other substances com rising a cup of sheet metal arranged to t over a cake of the substance and havin' a fluted exterior of such len h as to have Ton g bearing there upon and ing provided on its fiat face gaged by said with apertures having cutting edges adjacent thereto, a follower arranged to en age with a cylindrical cake of material an rotate therewith, and a screw threaded rod fixed for rotation with the cup and arranged to engage a screw threaded aperture in the follower for feeding the latter toward the cup.

-3. A device for shaving or shredding wax or other substances, comprisin a on formed of sheet metal of considera le dept and provided with a flat head having slits, the metal ad'acent to each slit being bent inwardly an outwardly on opposite sides of the'slit to form inner and outer cutters, said cup being adapted to serve as a measure forsubstances shaved or shredded thereby.

4. A device for shaving or shredding wax and other substances, comprising a cylindrical cup of sheet metal arranged to. fit loosely over a cylindrical cake and having a flat head and a flange of such length as to have substantial su port thereon, and provided on its flat hea with openings hav: ing one edge bent inwardly and one edge bent outwardl to form iImer and outer cutters, a threa ed rod secured to said cup, and a follower engaged b said rod and arranged to bear against the opposite end of the cake.

5. A device for shaving or shredding wax or other substances, comprising a cup formed of sheet metal having a fiat head and a flange of considerable depth, said flat head being formed with openings therethrough and with cutters on both of its faces adjacent to said openings, either set of said cutters being adapted to shave or shred wax or other material, and the cup being adapted either to be laced over a cake of the material and to e supported thereby with the inner face of the head in contact therewith to shave the same, or to' be moved over a cake of the material with the outer face of the .head in contact therewith to collect the shaved material in the cup.

In testimony whereof, I have hereunto set my hand.
